Description

  The present invention relates to a system and method for controlling and monitoring an aircraft, and more particularly to control the temperature at an air vent and to monitor an excess of a predetermined temperature threshold in the aircraft. Related to the system.

  For example, a known aircraft such as an airplane includes a fuselage including a cockpit deck and a cabin, and at least one engine set. Such an engine set includes an engine and a blower capable of performing air bleeding. Such extraction is performed by a system called an air extraction system, and includes a plurality of valves and a precooler. These valves allow the flow of high-pressure, high-temperature air, for example, extracted by the engine, and the flow of cooler, lower temperature, medium-pressure, extracted by the engine, in various air streams circulating in and around the engine. , And the air in the air flow of the cold blower extracted by the blower can be taken out. The high pressure air stream and the medium pressure air stream can be mixed into a mixed stream supplied to the precooler. At this time, the precooler enables heat exchange between the mixed stream and the airflow of the blower, and the temperature of the mixed stream at the outlet of the precooler, for example, to supply the airflow to the aircraft cockpit or cabin at a regulated temperature. It is possible to lower.

  Such adjustment is obtained by controlling the opening of one or more of the air extraction valves. The temperature of the airflow can be adjusted by selecting one or more valves to be controlled, for example by controlling the opening or closing of the blower air extraction valve.

  On the one hand, the temperature is controlled to allow the opening or closing of one or more valves, and on the other hand, the closing of one or more valves, eg hot vent valves, or a predetermined temperature threshold. Systems are known in which the exceeding of the threshold is monitored in order to allow the opening of one or more valves, for example a cold vent valve, in the event that is exceeded. Such an overshoot occurs, for example, when the temperature of the extracted air intended for the cockpit is too high, and this type of event is classified as catastrophic with respect to aircraft safety.

  Known air bleed systems comprise a thermostat that is directly connected to one or more valves and allows the temperature of the air drawn by the one or more valves to be controlled. The opening is adjusted by a thermostat signal. However, such a thermostat actually induces an error in the temperature measurement and hence in the control of the measurement.

  One existing solution is to measure the temperature of the flow obtained from the precooler and place a temperature sensor to report this measurement to an air extraction system management computer dedicated to the air extraction system. At this time, the officially obtained measurement value allows the computer to perform both control of the temperature of the extracted air and monitoring for exceeding a predetermined temperature threshold according to the temperature of the extracted air. However, using such measurements actually induces a common mode problem. In practice, control and monitoring in this case are dependent on the same temperature measurement at the same time, so an incorrect measurement will result in inadequate control of the extracted air temperature and the predetermined extracted air temperature. It means both insufficient monitoring of exceeding thresholds, which presents a problem with aircraft safety.

The object of the present invention is to partially eliminate these drawbacks. To achieve this object, the present invention is an air bleed system for an aircraft, comprising:
At least one air extraction valve suitable for extracting airflow in an aircraft;
A first temperature information module configured to determine and transmit temperature information of the first extracted airflow via the first acquisition channel;
A second temperature information module configured to determine and transmit temperature information of the second extracted airflow via the second acquisition channel;
At least one management module coupled to the data processing module,
On the one hand, via the first acquisition channel, the temperature information of the first extracted air flow enabling the corresponding air extraction valve control and / or on the other hand, via the second acquisition channel Receiving temperature information of a second extracted airflow that enables monitoring of the temperature threshold of the extracted airflow being exceeded;
At least one management module configured to transmit the first temperature information and the second temperature information;
At least one data processing module coupled to the management module,
Receiving the temperature information of the first extracted airflow via the first processing channel and enabling the corresponding air extraction valve control;
Via a second processing channel, receiving temperature information of a second extracted airflow that allows a temperature threshold exceeding a predetermined extracted airflow to be monitored, said threshold being And at least one data processing module configured to allow closure of at least one air vent valve if exceeded.

  The term “extracting airflow with an aircraft” should be understood herein to mean the act of extracting air from a stream circulating in an aircraft blower or engine, for example.

  “Acquisition channel” should be understood to mean a communication channel suitable for allowing transmission of information transmitted by an information module.

  “Processing channel” is to be understood as meaning a communication channel suitable for allowing transmission of information to the processing module, which can be identical to the acquisition channel, ie the acquisition channel. Can be integrated with.

  “Temperature information” should be understood to mean a temperature measurement or a temperature threshold exceeded condition.

  The term “determining” should be understood to mean measuring the temperature or establishing a condition in which a predetermined temperature threshold is exceeded by the temperature of the extracted airflow.

  “Over temperature threshold condition” should be understood to mean a binary or Boolean result of the type “threshold exceeded” or “do not exceed threshold”. The state can be binary or can take the form of discrete values, for example.

  It will be noted that the threshold can be set at a given moment, but can then be modified, for example, to allow the module to operate in a reduced mode.

  Thus, the temperature information received from the management module by the data processing module can comprise, for example, a temperature measurement value or a value corresponding to a condition that exceeds a predetermined temperature threshold.

  Thus, such a system controls the temperature of the extracted air based on two temperature information items obtained via two different acquisition channels, and monitors for exceeding a predetermined extracted air temperature threshold. Both can be done. In other words, the first information module makes it possible to obtain the first temperature information in order to perform the control function, while the second information module performs the monitoring function. The second temperature information can be acquired. Thus, there is no longer any common mode between control and monitoring. In addition, control and monitoring is performed based on accurate temperature information, for example, based on a measured value or a given condition exceeding a predetermined temperature threshold.

  Advantageously, the system comprises a high pressure air vent valve, a medium pressure air vent valve, a blower air vent valve and a precooler, wherein the airflow drawn by the high pressure air vent valve is mixed at the precooler inlet. In order to re-cool the mixed stream by heat exchange with the air stream extracted by the air extraction valve of the blower. Is suitable.

  Preferably, the first temperature information module is configured to measure and transmit a temperature measurement of the first extracted airflow via the first acquisition channel, and the second temperature information module is Measuring and transmitting a temperature measurement of the second extracted airflow via the second acquisition channel, or a predetermined temperature depending on the temperature of the extracted airflow via the second acquisition channel It is configured to determine and transmit a threshold exceeded condition.

According to one aspect of the invention, the management module is
Configured to convert the received airflow temperature measurement into a numerical value and / or to compare the received airflow temperature information with a predetermined threshold. An analysis module;
A transmission module configured to transmit the numerical value and / or the result of the comparison.

  In particular, the management module can be suitable for converting received analog temperature measurements into digital values that can be used, for example, by a processor or by a field programmable gate array (FPGA). .

  Advantageously, the aircraft comprises a computer and a management module, the data processing module being implemented by said computer. As is well known, the computer includes information processing means configured to process data and to implement a computer program. The computer can be, for example, an aircraft engine computer used to manage information regarding the operation of one or more engines of the aircraft. By using an aircraft engine computer, avoid using an additional computer dedicated to the management of the aircraft's air bleed system, and therefore control the aircraft's air bleed system and engine in a centralized manner Is possible.

  According to one aspect of the invention, the first temperature information module is configured to measure and transmit a temperature measurement of the first extracted airflow via the first acquisition channel, and The second temperature information module is configured to measure and transmit a temperature measurement value of the second extracted airflow via the second acquisition channel, and the management module is configured to transmit the second temperature information module from the first temperature information module. Suitable for receiving the first measurement value via a first acquisition channel and the second measurement value via a second acquisition channel from a second temperature information module, the management module is a processing module And the first and second processing channels are the same.

  Therefore, the first information module can obtain the first temperature measurement value to execute the control function, while the second information module can execute the monitoring function to execute the monitoring function. Two temperature measurements can be obtained and the two measurements are then transmitted by a single management module to a single processing module interconnected by a single channel. Therefore, the two temperature information items are separated up to the management module.

  According to one aspect of the invention, the system is also coupled to the second data processing module by the third and fourth identical processing channels and on the one hand to the first temperature information module and on the other hand to the second temperature. A second management module coupled to the information module, wherein the second management module receives the first measurement value from the first temperature information module via the third acquisition channel, and the second temperature information module To receive the second measurement value via the fourth acquisition channel.

  Such a configuration, for example, reports temperature measurements from different temperature information modules (respectively from the first temperature information module and from the second temperature information module, respectively), for example on the first physical channel of the computer. Temperature measurements from different temperature information modules (from the first temperature information module and from the second temperature information module, respectively) on the first physical channel and the second channel, and on the second physical channel Can be combined with the first channel and the second channel, respectively. By using two physical channels, it becomes possible to divide the management functions of the management module so that if one of the management modules does not operate correctly, the other can guarantee the function of one.

  According to another feature of the invention, the first temperature information module is configured to measure and transmit a temperature measurement of the first extracted airflow via the first acquisition channel, The second temperature information module is configured to determine and transmit a condition of exceeding a predetermined temperature threshold according to the temperature of the extracted airflow via the second acquisition channel, and the management module includes: The temperature measurement value is received via the first acquisition channel and the excess condition is received via the second acquisition channel, and the first and second processing channels are identical.

  Accordingly, the first information module can obtain a temperature measurement value to execute the control function, while the second information module can perform a predetermined temperature to execute the monitoring function. It is possible to obtain an over-threshold condition and the two information items are in this case transmitted by the single management module to a single processing module interconnected by a single channel. Therefore, the two temperature information items are separated up to the management module.

  According to another feature of the invention, the first temperature information module is configured to measure and transmit a temperature measurement of the first extracted airflow via the first acquisition channel, The second information module is configured to determine and transmit a condition of exceeding a predetermined temperature threshold according to the temperature of the extracted air current via the second acquisition channel, and the management module And the data processing module is configured to receive an excess condition via the second acquisition channel, wherein the second acquisition channel and the second acquisition channel are configured to receive the temperature measurement via the one acquisition channel. The processing channel is the same.

  Therefore, the first information module can obtain a temperature measurement value for executing the control function, while the second information module can execute the monitoring function with a predetermined temperature threshold. It becomes possible to acquire the state of exceeding the value. In this case, only the measured value is transmitted to the single management module, and the status is transmitted directly to the single data processing module by the second information module. Thus, the two temperature information items are separated up to the data processing module.

  According to another feature of the invention, the first temperature information module is configured to measure and transmit a temperature measurement of the first extracted airflow via the first acquisition channel, The second temperature information module is configured to determine and transmit a condition of exceeding a predetermined temperature threshold according to the temperature of the extracted airflow via the second acquisition channel, and the management module includes: The temperature acquisition value is received via the first acquisition channel and the excess condition is received via the second acquisition channel, and the second acquisition channel and the second processing channel are different.

  Thus, the first information module can obtain temperature information for executing the control function, while the second information module can execute the monitoring function with a predetermined temperature threshold. It becomes possible to acquire the state of exceeding the value. In this case, the two temperature information items are transmitted to the single management module, but the measured value is transmitted to the single processing module via the first processing channel, and the status is transmitted via the second processing channel. Sent to a single data processing module, which allows two temperature information items to be separated up to the data processing module.

  According to another feature of the invention, the system includes a first data processing module configured to receive first temperature information via a first processing channel, and a second processing channel. A second data processing module configured to receive the second temperature information.

  Therefore, the control of the temperature of the extracted air and the monitoring of exceeding the predetermined extracted air temperature threshold can be separated between the two data processing modules, i.e. between the two computers of the aircraft, for example. This makes it possible to increase the safety of the aircraft in view of the fact that one failure of the computer only results in the loss of one of the control or monitoring functions.

  According to another feature of the invention, the second data processing module is configured to transmit second temperature information to the first data processing module. This state can be transmitted directly or via, for example, a communication module.

  According to another feature of the invention, the system also comprises a third data processing module configured to receive the first temperature information via the third processing channel.

  Thereby, it becomes possible to secure acquisition of the first temperature information by dividing one of the processing modules.

  The system according to the present invention has been described above with reference to temperature measurements or conditions exceeding a predetermined temperature threshold. However, the present invention also provides other measurements, eg, pressure measurements, or a predetermined pressure to control the opening and / or closing of one or more valves of an aircraft air bleed system. It should be noted that this can be applied to threshold overage conditions.

  An air bleed system 1 according to the invention, shown in FIG. 1 a, circulates in two air bleed valves 5 and 5 ′ in the air stream circulating in the aircraft engine 2 and in the blower of the aircraft engine 2. And an air bleed valve 5 ".

  The valve 5 can be, for example, an extraction valve in a medium-pressure air stream extracted by the engine, while the valve 5 'can be, for example, in a higher-temperature, high-pressure air stream extracted by the engine. It can be a withdrawal valve. The valve 5 "makes it possible to extract the cold airflow directly with a blower upstream of the aircraft engine 2.

  The air flow extracted by the engine by the air extraction valves 5, 5 ′ is mixed into the mixed stream upstream of the precooler 6. The precooler enables heat exchange between the mixed flow and the airflow of the blower, and the temperature of the mixed flow F obtained at the precooler outlet can be lowered. The mixed stream F obtained at the regulated temperature is routed by the duct 7, for example via an air conditioning system, to the cockpit, to the passenger cabin or to prevent winging of the aircraft wings.

  Such adjustment is obtained by controlling the opening of one or more air extraction valves 5, 5 ', 5 ". In particular, the temperature of the air flow is determined by the opening or closing of the air extraction valve 5" of the blower. It can be adjusted by controlling the closure and / or by selecting one or more valves 5, 5 ', 5 "to be controlled.

  The system 1 also includes a first temperature information module 10, a second temperature information module 20, at least one management module 30, and at least one data processing module 40 coupled to the management module 30.

  The first temperature information module 10 is configured to measure and transmit a first temperature measurement value of the extracted air flow F circulating in the duct 7 via the first acquisition channel 15. The

  The second temperature information module 20 measures and transmits a second temperature measurement value of the extracted air flow F circulating in the duct 7 via the second acquisition channel 25, or Via the second acquisition channel 25, the temperature of the extracted air flow F circulating in the duct 7 is determined according to the temperature exceeding the predetermined temperature threshold and transmitted.

  One or more management modules 30 are coupled to at least one data processing module 40 and receive temperature information received from the first temperature information module 10 and from the second temperature information module 20 to the data processing module 40. Configured to send to.

  The one or more data processing modules 40 are coupled to the management module 30 and send commands to the air vent valve in response to information received from the management module 30 or from the temperature information module (10, 20). Configured to control the opening or closing of one or more of 5, 5 ′, 5 ″.

  The data processing module 40 may comprise or be coupled to a memory (not shown) configured to store computer programs. Such a program allows processing of temperature information and can be designed to send open and close commands to the valves 5, 5 ', 5 "of the aircraft bleed system.

  For example, to perform a control function, the data processing module 40 measures the difference between the received temperature and a reference temperature and enables proportional operation of one of the valves, for example, the air extraction valve of the blower.

  Similarly, to perform a monitoring function, for example, the data processing module 40 determines whether the received measurement exceeds a threshold value, or the received condition closes the blower air vent valve. It can be determined even if it indicates an excess condition to be enabled.

  Thus, in the system according to the present invention, the management module makes it possible in particular to obtain and format temperature information, and the data processing module analyzes the temperature information received from the management module and possibly deflates the aircraft. It is possible to activate one or more of the valves of the system. The operation of the air vent valve can be performed by the processing module 40 itself, or the processing module can, for example, allow the pilot to manually operate one or more air vent valves elsewhere. Alert messages can be sent to other modules or systems, such as modules for monitoring aircraft cabins.

  In one embodiment of the system according to the invention, the valves 5, 5 ′, 5 ″ are remotely controlled by the data processing module 40 or by other modules of the aircraft, for example a module for manual monitoring by a pilot. In an alternative embodiment, the valve may be independently present, for example a medium pressure vent valve, for example a spring operated pneumatic valve that is self-adjusting according to its end pressure, and At this time, the data processing module is suitable for controlling the other two valves.

  In the first embodiment shown in FIG. 1 b, the system 101 includes a first temperature information module 110, a second temperature information module 120, a management module 130, and a data processing module 140.

  The first temperature information module 110 may be a temperature measurement probe, for example. The second temperature information module 120 can be, for example, a second temperature measurement probe or a thermocouple known to those skilled in the art.

  The management module 130 is coupled or connected to the first temperature information module 110 on the one hand and to the second temperature information module 120 on the other hand.

  In this embodiment, the first temperature information module 110 and the second temperature information module 120 are two temperature measurement probes. Accordingly, the first temperature information module 110 and the second temperature information module 120 are configured to measure the temperature of the extracted air flow F circulating in the duct 107 of the air extraction system 101.

  The management module 130 obtains the temperature measurement value M1 of the first extracted airflow from the first measurement probe 110 via the first acquisition channel 115 and the second acquisition channel 125 from the second measurement probe 120. It is suitable for receiving the temperature measurement value M2 of the second extracted airflow.

  The management module 130 includes temperature control means 132 configured to supply the temperature measurement value M1 supplied by the first temperature information module 110 to the data processing module 140 via the processing channel 135.

  The data processing module 140 processes the received measurement value M1 so that the temperature of the airflow F can be adjusted to a desired value and the one or more valves 5, 5 ′, 5 ″. The control is configured to allow opening or closing of these valves.

  The management module 130 also comprises means 134 for monitoring the condition of exceeding a predetermined temperature threshold according to the temperature of the extracted airflow. These monitoring means 134 are configured to supply the second measurement value M2 obtained from the second probe 120 to the data processing module 140 via the processing channel 135.

  The data processing module 140 is configured to determine an over-threshold condition, i.e., whether the temperature corresponding to the second measured value M2 has exceeded a predetermined threshold.

  In one embodiment shown in FIG. 2b, which complements the first embodiment shown in FIG. 2a, the system is the same as the module 140 and the second management module 130 ′, which is the same as the module 130, and the management. A second data processing module 140 ′ coupled to module 130 ′, a third acquisition channel 115 ′ and a fourth acquisition channel 125 ′ may be provided. Thus, modules 130 and 140 and means 132 and 134 are divided into two similar acquisition channels 115 and 125.

  The first management module 130 is coupled or connected to the first temperature information module 110 on the one hand and to the second temperature information module 120 on the other hand.

  The second management module 130 ′ is coupled to the first temperature information module 110 on the one hand by a third acquisition channel 115 ′ and on the other hand to the second temperature information module 120 by a fourth acquisition channel 125 ′. Or connected.

  In this embodiment, the first temperature information module 110 and the second temperature information module 120 are two temperature measurement probes.

  The first management module 130 obtains the temperature measurement value M1 of the first extracted air flow from the first measurement probe 110 via the first acquisition channel 115 and the second acquisition from the second measurement probe 120. Suitable for receiving a second measured airflow temperature measurement M2 via channel 125.

  The second management module 130 ′ obtains the temperature measurement value M1 of the first extracted air flow from the first measurement probe 110 via the third acquisition channel 115 ′ and the fourth measurement probe 120 to the fourth. Is suitable for receiving the second extracted airflow temperature measurement M2 via the acquisition channel 125 ′.

  The first management module 130 includes temperature control means 132 configured to supply the data processing module 140 with the temperature measurement value M1 supplied by the first temperature information module 110 via the processing channel 135. At this time, the data processing module 140 processes the received measurement values to allow control of the air bleed valve of the aircraft to adjust the temperature of the airflow F.

  The first management module 130 also comprises means 134 for monitoring the condition of exceeding a predetermined temperature threshold according to the temperature of the extracted airflow F. At this time, the monitoring means 134 supplies the second measurement value M2 obtained from the second probe 120 to the data processing module 140 via the processing channel 135, and then the data processing module 140 performs the monitoring function. To do so, an over-threshold condition is used to make valves 5, 5 ', 5 "controllable or uncontrollable.

  Similarly, the second management module 130 ′ is configured to supply the temperature measurement value M1 supplied by the first temperature information module 110 to the data processing module 140 ′ via the processing channel 135 ′. Control means 132 'is provided. At this time, the data processing module 140 'processes the received measurements to allow control of the air bleed valves 5, 5', 5 "of the aircraft to adjust the temperature of the airflow F.

  The second management module 130 'also comprises means 134' for monitoring the condition of exceeding a predetermined temperature threshold according to the temperature of the extracted airflow.

  At this time, the monitoring means 134 ′ supplies the second measurement value M2 obtained from the second probe 120 to the data processing module 140 ′ via the processing channel 135 ′, and then the data processing module 140 ′ In order to perform the monitoring function, the over-threshold condition is used to make the valves 5, 5 ', 5 "controllable or uncontrollable.

  Thus, this embodiment of the system according to the invention makes it possible to report the temperature measurements M1 and M2 respectively measured by the probes 110 and 120 via four acquisition channels instead of two. In other words, each measurement is reported twice to different data processing modules via different acquisition channels. Considering that such module and channel redundancy does not result in the loss of one of the modules resulting in the loss of the two measurements remaining on the other management module, useful for control and monitoring functions, It becomes possible to enhance the reliability of control and monitoring. Such an architecture can be easily implemented on aircraft computers, such as so-called “engine” computers. Such a known computer may actually comprise two data processing modules that each communicate via a physical data communication channel. The management module can be installed on a computer that is coupled on the one hand to its respective data processing module and on the other hand connected to two probes by two channels, respectively. One channel is linked to one and the same physical communication channel of the computer.

Configured to do.

  The condition of exceeding a predetermined extracted air temperature threshold determined by the information module 220 may take the form of a discrete value comprising, for example, a circuit value, or a binary or Boolean value. For example, a low state (open circuit) of discrete values can correspond to an airflow temperature higher than a threshold, and a high state (closed circuit) corresponds to not reaching the threshold. And vice versa. The binary result can be, for example, 0 or 1 received via a digital bus from another information module (eg, another computer). This excess condition is provided by the information module 220 directly to the field programmable gate array (FPGA) 260 for processing.

FPGA 260 communicates with FPGA 270 coupled to processor 280 via processing channel 235 for processor 280 to process data received from management module 230. In other words, the FPGA 270 specifically ensures management of communication between the management module 230 and the processor 280.

  In the fourth embodiment shown in FIG. 3, the system 301 includes a temperature measurement probe 310, a temperature threshold excess state information module 320, a management module 330, and a data processing module 340.

  The management module 330 is connected to the measurement probe 310 by a first acquisition channel 315, while the data processing module 340 is in this case connected to the information module 320 by a second acquisition channel 325 integrated with the processing channel. .
